Abstrakt: Background: Ceruloplasmin (Cp) is the most important serum copper transport protein playing a key role in the binding of iron to transferrin. It is a positive acute-phase response protein and the first-level diagnostic marker for Wilson disease and aceruloplasminemia. However, standardization of Cp measurement has not been successful, and assay specific reference levels of Cp are required.
Methods: From May 2019 to July 2022, we enrolled 1706 consecutive healthy Italian blood donors (1285 men and 421 women, 18 to 65 years) to identify the reference intervals of serum Cp through quantile regression and evaluate the relationship of Cp with age, sex, iron, and metabolic status through linear regression.
Results: We found that mean serum Cp was influenced by sex and slightly by age. The lower reference Cp value rose slightly with increasing age in both men and women. The upper reference value increased, reaching a plateau of about 25 mg/dL around 25 years in men, while in women it initially increased to around 45 mg/dL in young adults to fall sharply below 30 mg/dL for adults after their fifties.
Conclusions: We showed that the normal reference curves of serum Cp vary according to sex in a large population of healthy adults. While the lower reference values did not appear to be influenced by age and sex, the upper ones differed according to sex and age showing a particularly high variability in women, possibly reflecting different hormonal status.
